Think the £10 off a £50 spend voucher only applies to new customers on Tesco Direct, but thought this would be useful for some.
Works out as a cheap way to get the game, and some Xbox Live & Clubcard points which always come in handy.
Forza could be replaced with any of the other pre-orders - Assassins Creed 2, Left 4 Dead 2 etc.
Should be £5 delivery for the points card but seems to knock that off as it's alongside a pre-order game.
EDIT - appears the code isn't appearing below as it's in the wrong merchant category. The voucher is here - http://www.hotukdeals.com/item/498596/tesco-direct-10-off-your-first-shop
